Portable and mobile RF communications
equipment should be used no closer to
any part of the CXDI-55G, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the trans-
mitter.
Recommended separations distance
where P is the maximum output power rat-
ing of the transmitter in watts (W) accord-
ing to the transmitter manufacturer and d
is the recommended separation distance
in metres (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey

.
Interference may occur in the vicinity of
equipment marked with the following sym-
bol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflections from structures, object and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) tele-
phones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast can-
not be predicted theoretically with accuracy. To assess the electromagnetic environment due to
fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field
strength in the location in which the CXDI-55G is used exceeds the applicable RF compliance level
above, the CXDI-55G should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the CXDI-55G.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
